Core alphabet concept and free function/type trait wrappers.
A wrapper type around an existing view adaptor that enables "deep view" behaviour for that view.
Definition: deep.hpp:104
constexpr auto assign_char_to
Assign a character to an alphabet object.
Definition: concept.hpp:523
decltype(seqan3::to_char(std::declval< alphabet_type const >())) alphabet_char_t
The char_type of the alphabet; defined as the return type of seqan3::to_char.
Definition: concept.hpp:396
decltype(detail::transform< trait_t >(list_t{})) transform
Apply a transformation trait to every type in the list and return a seqan3::type_list of the results.
Definition: traits.hpp:471
auto const char_to
A view over an alphabet, given a range of characters.
Definition: char_to.hpp:72
The SeqAn namespace for views.
Definition: char_to.hpp:22
Adaptations of concepts from the Ranges TS.
Provides various type traits on generic types.
Provides seqan3::views::deep.
